Tons of snippets are lying around, but few have 3D-SU goals/concept. What I would tell is that SU is specific for concepts relating to 3D expressions. Such concepts would first be enumerated: concept of rotating , concepts of translation, and so on. A master of SU-Ruby (I am keen to tell Gouru for their overwhelming production under rbs label --with some exceptions--) would express a concept with easyness parcimony, not at the hand of a novice. And then the motivated novice, I am sure will test the snippet, rearrange it and ONE day childbirth (!) snippets which will became a plugin NOT rbs one.
Cogitations or Hallucinations, it's up to you to judge.
I am ashamed to tell thanks for my ignorance.
